Installing and wiring Warning — 40200 and 42230 controls must be installed and serviced  only by a qualified service technician.

1. Always disconnec disconnectt power sourc sourcee before before wiring to avoid avoid electrical electrical shock shock or damage to the control. All wiring must comply with applicable codes and ordinances. 2. Ther Thermost mostat at terminals terminals (T–T) (T–T) provide provide a current current source. source. Never Never apply external power to these terminals under any circumstances. Mounting

Field checks

(1) The 40200 & 42230 controls provide two motor relays. Carlin’s patented SMC technology technology (Safety Monitoring Circuit) monitors the contacts of both motor relays. Lockout occurs if a motor relay contact is found closed when it should be open. The second motor relay ensures motor shutdown even if the first motor relay fails.

1. Safety timing (TFI) test — cel l wire (F-F). Start S tart burner. test — Remove one cad cell The control should lockout within 15 seconds (40200) or 30 seconds (42230). Replace cad cell wire. 2. Flame failure test — test — Start burner. After flame is established (after TFI period), close the oil supply hand valve. This will cause a flame failure sequence as described on the reverse side of this Data sheet. 3.

Model 40200/42230 Cad cell Oil primary controls — Data sheet — Operation/Troubleshooting

Start-up & operation Do not start the burner if the combustion chamber contains oil or oil vapor vapor.. Per UL requirements, the control will not turn on if the cad cell senses flame during the selftest. If the cad cell sees light (flame) at the beginning of a cycle, the control will wait until it no longer senses the problem. Power ON

Open all manual oil line valves. Close the line switch.

Reset

Press and hold the reset button for 3 seconds, then release. This will reset the control at any time during its operation.

Stand-by

(No call for heat) Control waits for power to be applied to the black wire (from appliance limit circuit).

Call for heat

Set thermostat (or limit) to call for heat. Thermostat circuit must be closed and power coming to black wire from limit circuit.

Burner on

The ignitor  and  and motor start.

TFI

The cad cell must sense flame within the control’s trial for ignition (TFI) timing — 15 seconds for 40200 control or 30 seconds for 42230 control. After cad cell senses flame, the ignitor stays on another 10 seconds (flame stabilization period).

Run

The burner continues firing during call for heat if the cad cell is sensing flame.

Lockout

If cad cell does not sense flame within the TFI timing (15 or 30 seconds), lockout occurs.

To Reset

Push in and hold reset button for 3 seconds, then release. This will reset control at any time during operation.

Flame failure

If the cad cell loses flame signal during operation (after the TFI), the burner shuts off within 1.3 seconds. Recycle Recycle:: After 60 to 90 seconds the control will restart ( Burner on  mode).  mode).

Burner off

Set thermostat (or aquastat) to stop call for heat. The burner shuts off within 2 seconds after end of call for heat.

Stand-by

Control remains in stand-by mode until limit circuit sends power to the black wire and T-T circuit closes (call for heat).

Power loss

If power to control/burner is interrupted during a normal run cycle, the control will begin a normal cycle again after power is restored.

To troubleshoot: • Check CAD cell by cell by unplugging it and measuring the resistance across its pins: dark resistance at least 50 KOHMS; room light resistance less than 10 KOHMS. Replace if necessary. If the CAD cell functions properly, reinstall the cell and close the burner housing. light by measuring the CAD cell resistance • Check for stray light by looking into the inactive combustion chamber. It should read at least 50 KOHMS. Control will not reset • If the control will not reset, reset, the the Safety Monitor Monitoring ing Circui Circuitt may be detecting an internal control problem.
